Cucumber dressing for gyros

I’m making gyros tonight for supper but cannot find my recipe for the creamy cucumber dressing ! Can anyone help? I believe the ingredients included yogurt, sour cream and of course cucumbers…

1 cucumber, peeled and seeded
1 8-ounce container sour cream
1 clove garlic, crushed
1/2 teaspoon salt

Grate cucumber, and drain excess liquid between paper towels, combine all ingredients and chill at least 30 minutes before serving.
